from month my system was restarting first i though it was a power suply problem then i figured it out my temps were quit high on idle cpu 75-80 degree Celsius
i applied thermal paste on my intel stock cooler and temps are looking normal like 40 on idle and watching movies or using browser temps are not more then 50 but on playing games like dota 2 my temp is reaching 80-82 is that fine ?
i am thinking of buying a new cpu cololer for that purpose of low budget i dont over clock
plz tell any low budget but good performance cooler from site below

thanks
